Richie Incognito filed a grievance Thursday against the Miami Dolphins over his suspension.
The NFL Players Association released a statement late in the afternoon saying the veteran guard filed a non-injury grievance.
The grievance challenges his suspension for conduct which was alleged to have occurred while he was with the club, the unions statement said. In the grievance, Incognito requests that the hearing be held on an expedited basis so that he can immediately resume playing for the team.
The NFL Players Association will continue to protect the rights of all players.
Incognito was suspended by Miami on Nov. 3 for misconduct related to the treatment of teammate Jonathan Martin, who abruptly left the Dolphins late last month to receive help for emotional issues.
The NFL is investigating whether Incognito harassed or bullied Martin. Incognito has said the conduct was all part of the normal locker room environment.
ESPN first reported the grievance.
Incognito has missed one game, and the suspension by the team can last for four games. The Dolphins, who have not said how long Incognito is suspended, said they do not comment on grievances.
Martin is scheduled to meet today with Ted Wells, the independent investigator hired by the NFL. Dolphins owner Stephen Ross also plans to meet with Martin.
Peyton Manning was back at practice for the Broncos, listed as limited on Denvers injury report but looking more and more like a sure thing to play Sunday.
He practiced a good bit and looked like he was doing the things he needs to do for us, interim head coach Jack Del Rio said.
Manning missed practice Wednesday to get more treatment on the right ankle he aggravated when Chargers defensive lineman Corey Liuget dived at the quarterbacks lower legs toward the end of last Sundays game.
Both Del Rio and Manning have insisted Manning will play Sunday when the Broncos (8-1) play host to the Chiefs (9-0) with first place in the AFC West on the line.
